类 MaxAbsScaler

java.lang.Object

org.apache.flink.ml.feature.maxabsscaler.MaxAbsScaler

所有已实现的接口:

Serializable, org.apache.flink.ml.api.Estimator<MaxAbsScaler,MaxAbsScalerModel>, org.apache.flink.ml.api.Stage<MaxAbsScaler>, org.apache.flink.ml.common.param.HasInputCol<MaxAbsScaler>, org.apache.flink.ml.common.param.HasOutputCol<MaxAbsScaler>, MaxAbsScalerParams<MaxAbsScaler>, org.apache.flink.ml.param.WithParams<MaxAbsScaler>

public class MaxAbsScaler
extends Object
implements org.apache.flink.ml.api.Estimator<MaxAbsScaler,MaxAbsScalerModel>, MaxAbsScalerParams<MaxAbsScaler>

An Estimator which implements the MaxAbsScaler algorithm. This algorithm rescales feature values to the range [-1, 1] by dividing through the largest maximum absolute value in each feature. It does not shift/center the data and thus does not destroy any sparsity.
